DISINFECTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 429,384, dated June 3,1890.

Application filed. May 29,1889. Serial No. 312,525. (No model.)

To all whom it may concern.-

Be it known that I, MORRIS B. MANWARING, of Bayonne, in the county ofHudson and State of New Jersey, have invented a certain new and usefulImprovement in Disinfecting Devices, of which the following is aspecification.

The object of my invention is to provide a simple and effective devicewhereby disinfecting and antiseptic materials may be disseminated into areservoir of water. other object of the improvement is to provide adevice from which such materials may be liberated in the form of a gas.

I will describe a device embodying my improvement and then point out thenovel features in the claims.

In the accompanying drawings, Figure 1 is a side view of a deviceembodying my improvement. Fig. 2 is a top view thereof. Fig. 3 is a topview with a lid removed. Fig. 4 is a central vertical section thereof.

Similar letters of reference designate corresponding parts in all thefigures.

A designates a vessel adapted to contain disinfecting and antisepticmaterials and to fioat in a reservoir of water. The bottom is madesufficiently heavy as compared with the top or upper portion for gravityto insure it against being inverted. The interior surface a, Fig. 4, ofthe bottom is shown as slanting toward the center. In the presentinstance it is made concave.

I prefer to make the interior of the vessel cylindrical-above thebottom, as shown at a, Fig. 4, and the exterior of spherical,spheroidal, or analogous form. This form gives the device embodying myimprovement an attractive appearance, and also insures its floating inan upright position.

The device may advantageouslyvbe made of wood, although I do not wish toconfine myself to any special material. It may be made in one piece orof any desired number of pieces fastened together. Through the bottomextend two holes a a The one a extends from the lower part of theinterior bottom surface a through to the exterior of the bottom portion,and the other a extends from a higher part of the bottom surface athrough to the exterior of the bottom portion. An advantageous size forthese holes will be from about one thirty-second to one-sixteenth of aninch in diameter, according to the material contained in the vessel.

I have shown the vessel A as having a circular'opening a in the top.This may be fitted with any suitable cover. I have shown it as fittedwith a box-like cover B tapering downward externally, so that while itslower portion may pass through the opening its upper portion will fitwithin the opening and be supported in the same.

The cover B may have a lid 0. I have shown the upper edge of thebox-like cover extending above the opening a in the vessel A, and thelid 0 as provided with a rim or flange, which extends down around theexterior of the upper portion of the said cover.

The appearance of the vessel, its cover B, and the lid 0, when made ofwood may be enhanced by dipping the same in any coloring material-as,for instance, a solution of red aniline dye and draining and drying thesame. Then the parts will preferably have applied to them a coating ofmelted paraffine or other suitable material. This coating is to resistthe action of water entering the vessel, and also that of the materialcontained in the vessel.

The interior of the vessel is nearly filled with the disinfecting'orantiseptic material, the latter being in a disintegrated form and ofsuch character as to be soluble in Water. I prefer to use a materialwhich will form a highlycolored solution, because then the strength ofthe solution and the efficiency ofthe device maybe the more readilyappreciated.

The joint between the vessel A and the cover B is intended to bewater-tight. 0onsequen tly water can pass from the reservoir 'in whichthe vessel A is floated only through the holes C112 0. in the bottom. Itwill enter and form a solution'of the disinfecting or antisepticmaterial. This solution will be heavier than the water itself; hence acirculation will arise. This circulation will occur owing to the factthat one of the holes a euters the vessel at a point higher than theother. The water will ascend through the hole a and the solution willdescend through the hole a The circulation from the reservoir throughthe vessel and back again will be very slow, but is intended to besufficient to effect the dissemination of the disinfecting or antisepticmaterial throughout the water in the reservoir. The solution thus formedwill descend in the reservoir and any water flowing into the top of thereservoir to maintain the supply there will become iinpregated with thematerial in the vessel A. If a colored solution results from the use ofthe device, it will be easy for any one to ascertain when the deviceneeds replenishing. The fact that the device will rise as its contentsare consumed will, however, afford a sufficient indication that it needsreplenishing. The water will only rise a short distance in the vesselAas, for instance, to the dotted line a. As the material in that spaceenters into solution and passes off material descends from above tosupply its place. This water will not rise in the vessel A as high whenthe vessel is sealed as it would otherwise. I

The box-like cover may contain an y fibrous absorbent as, for instance,cotton or sponge-saturated with a suitably-volatile disinfecting orantiseptic material.

The lid C is not needed while the device is in use.

Pernianganate of potassium may be employed for a coloring-disinfectantin the vessel A. The box'like cover may advantageously be supplied withoil of thyme or a mixture of oil of thyme and oils of rosemary andlavender.

That I claim as my invention, and desire to secure by Letters Patent,is-

1. A device for disinfecting fluids, which consists of a hollowspheroidal structure of wood or other material and having a lessspecific gravity than the fluid in which it is to be used, provided witha cap and with orifices for ingress and egress of fluid and adapted tocontain a soluble disinfectant, substantially as specified.

2. A device for disinfecting fluids, which consists of a hollowspheroidal structure of wood or other material and having a lessspecific gravity than the fluid in which it is to be used, )rovided witha box-like cover adapted to receive an absorbent, and having orificesfor ingress and egress of fluid and adapted to contain a solubledisinfectant, substantially as specified.
